We conduct nonequilibrium molecular dynamics simulations to measure the shear stress sigma, the average inherent structure energy E{IS}, and the effective temperature T{eff} of a sheared model glass as a function of bath temperature T and shear strain rate gamma. For T above the glass transition temperature T0, the rheology approaches a Newtonian limit and T{eff}-->T as gamma-->0, while for T<T...

BACKGROUND The recent implementation of the dual energy technology on CT-scanners has opened new perspectives in tissue and material characterization. This study aims to evaluate whether dual energy CT can be used to assess the concentration of cocaine of intra-intestinal illegal packets. METHODS The study was approved by the institutional review board of our institution (CER 13_027_R). From ...

In mobile distributed environment, data broadcasting has many applications because it has two desirable characteristics: energy eciency and bandwidth eciency. There have been some researches on the indexing mechanisms for wireless data broadcasting in the past. We ®rst describe the problematic issue in the conventional index replication scheme, and then propose various index replication metho...

We discuss the possibility of using pair-equations for the construction of the effective Hamiltonian H eff for valence electrons of an atom. The low-energy part of atomic spectrum is found by solving the eigenvalue problem for H eff. In this way it is possible to account efficiently for the valence-valence and core-valence correlations. We tested this method on a toy model of a four-electron at...

The purpose of this work is to present a new method to extract the electron density ([Formula: see text]) and the effective atomic number (Z eff) from dual-energy CT images, based on a Karhunen-Loeve expansion (KLE) of the atomic cross section per electron. This method was used to calibrate a Siemens Definition CT using the CIRS phantom. The predicted electron density and effective atomic numbe...

Agronomic crops are produced across a variety of landscapes and climates and changes in climate impact their production effi ciency and potential greenhouse gas emissions and sequestration. Studies that reported the response of crops to climate change demonstrated the variation in response, the challenges that need to be addressed in evaluating these responses, and the interactions among natura...

This study aims at correlate Wmec and Cr with Eff. Twelve healthy men volunteered in the study. Wmec and Cr were measured during a treadmill running test which consisted in a rest period, incremental warm up and running test at 10km.h -1 . The biomechanical data, rest oxygen consumption (VO2) and exercise VO2 data were obtained. Relationships between variables were investigated using Pearson’s ...

The confined variational method is used to generate a basis of correlated Gaussians to describe the interaction region wave function for positron scattering from the H2 molecule. The scattering length was approximately = -2.7a(0) while the zero energy Z(eff) of 15.7 is compatible with experimental values. The variation of the scattering length and Z(eff) with internuclear distance was surprisin...

In the so-called Yukawaon model, the effective Yukawa coupling constants Y eff f (f = e, ν, u, d) are given by vacuum expectation values (VEVs) of gauge singlet scalars (Yukawaons) Yf with 3× 3 components, i.e. Y eff f = yf 〈Yf 〉/Λ, where Λ is an energy scale of the effective theory. In order to reveal characteristic features of the model, VEV structures and possible massless Yukawaons are inve...
